"The success of PS Plus is contributing in a big way to driving overall PSN sales, as our last quarter was the biggest in terms of transactional sales in PSN's six-year history," a spokesperson told Games Industry.biz.

"The immediate consumer reaction was completely off the charts, and membership sales more than doubled during the week of E3."

Launching in 2010, PlayStation Plus provides users with entire games and discounts, exclusive access to betas and demos and early access to certain new releases.
